convert a srw to a dually

[jatonka]

Well, I have a cheesy set of dual wheel adaptors for Chev 8 bolt hubs that are for the LT235/85r 16s that we use. I put them under my 79 Chev K20 to install a flatbed and Pac-Lift to service traffic signals, I had to jump curbs and do real out of level all the time and never had a problem with those spacers, but it sure stablized the truck so I didn't crash out of a 28' high platform lift. I have them, Would part with them if anyone wanted them. JT

The later dually pickups used 14 bolts instead a Dana 70. That's what I have under my '67 C-30. There are 3 different width 14 bolt FF rears - SRW, cab and chassis dually, and Dually pickup/short bus.

What Year did they use the 14 bolt Dually? IIRC 88+ GMC and 91+ Chevy had a wider SRW than previous. Also dont forget about vans They are different too. so there is more than 4 widths.

Yes, you're right, I was generally talking about 14 bolt rearends in these body styles. I'm not sure when the changeover year was, but I had a '87 dually pickup with a 14 bolt, and the one under my '67 C-30 came out of a '97 C3500.

should only be 2 widths in the 73-87 trucks. dually and srw. few diferent brake opp though

I say sell the truck and bid on a dually on GL I know I have seen a few for sale on there. Seems like A LOT less work.

put if wanted to do the easy thing i never would of join the corps.i think the gooseneck flatbed with som duels would work the best.the most heavy i haul is a 6000 pounds.i got a 84 k30 and a 06 chevy 3500 so anit really worried about haulen that much her

So as long as the dually rear was out of a pickup it should work?

 

[2deuce]

I thought it might be a cool option if the original bed takes too much of a beating and you wanted the stability of a dually.

Yes factory 1ton's all had the same spring spacing. just different widths

 

[kassim503]

+1 on the caddilac big block idea that is one fine motor

Pirate4x4.Com - Extreme Four Wheel Drive Pirate 4x4 has everything you need to know on most 14 bolt setups. Could a 105 trailer fit on the back as a bed?

This is my first CUCV, a 1008 I bought as a cab & chassis from a refuse district. I took the 14 bolt duel rear from a 1979 C-30. Differential 4.56 with locker is from cucv axel. Worked this truck for 10 years. I know some folks would convert the front axel to duelly type rims, but I kind of like it the way it is. Used the truck locally and have lots of spares of both types of rims, so it was never a problem. If you change out differential chuck, follow bearing pre-load instructions from good chevy manual. I use the factory one. I added new HD springs plus 4 leaf helper spring packs from C-30. Helper spring rests cut from C-30. Holes are already drilled in 1008 frame. It helps to look a stock duelly to position them. Use grade 8 bolts.

 

[XanRa]

heck if your doing it because you want to- why not go ahead and run duels all the way around

 

[dependable]

heck, I put together this truck to work, no need to pay for duel wheel rim adapters in front. This truck has been great. Paid for itself in my business many times.

73-87 Dual wheel trucks had 2 widths, Cab and Chassis was narrow compared to a factory dually Bed trucks, then of coarse you had the SRW trucks and vans. The cucv dually that I had did have the adapters and fenders added to it to make it a dually I got it straight from GL like that.
